Configurable via `doc_path` for repos that maintain a + different doc. — `action.yml`, `decisions.py` + +2. **REST API over MCP.** The card allows either surface. A CI runner has no + MCP server dependency, and the four-call contract (upload, chat, approve, + export) is the same on both surfaces. The MCP tool mapping is documented in + the README. — `superdocs_client.py` + +3. **The machine approves the proposed change; the human reviews the PR.** + The card's "Review" surface is satisfied by `approval_mode: + ask_every_time` + the approve call (the gate is an operation the flow + exposes, exactly as behavior 4 of the shared task requires), and the human + review is the pull request itself — the durable artifact the card asks for. + The API auto-denies unattended reviews after ~1h, so a PR-gated flow is the + only shape that survives CI latency. — `main.py` + +4. **The merged PR's title/body are untrusted data.** They are quoted into the + instruction as data, never executed as instructions, and the edit is scoped + to one changelog entry. Tested: a title that tries to give orders produces + a data-only entry. — `decisions.py::build_instruction`, + `tests::InstructionBuilderTests` + +5. **"Nothing needs saying" has five independent triggers.** Docs-only PR, + skip marker, no change from SuperDocs (byte-identical export), entry + already present, docs PR already open. Each is a separate early exit so a + skip is provable, not assumed. — `decisions.py`, `main.py` + +6. **The `pull_request.closed` event does not carry the file list.** The + action derives changed files from the merge commit (`git diff sha^1 sha`), + which is why checkout uses `fetch-depth: 0`. — `main.py` + +7. **Proposed-change content can arrive as a JSON-encoded string.** The task + doc warns this is the most common integration trap; the client parses both + shapes. — `superdocs_client.py::_parse_changes`, tested. + +8. **`awaiting_approval` has two flavours.** `continue_prompt` (large edit + paused) is resumed via `/continue`, never `/approve`; the client branches on + `metadata.awaiting_kind` exactly as the docs require. — tested. + +9. **A docs PR for a merge that already exists is a duplicate.** Idempotency + is checked by searching open PRs with the same title before doing any work. + — `main.py::_existing_docs_pr`, tested. + +## Cuts (defended) + +- **No per-change human approval inside the action.** The card's review is the + PR; a second approval round inside CI would block on a human who is not + watching CI. The PR diff is the review surface. +- **No MCP mode.** REST covers the contract; MCP would add a server dependency + to the runner for no behavioral gain. Documented as a future option. +- **No multi-doc support.** The action maintains one doc file per repo; a + multi-file mode would multiply operations per merge for little value. +- **No PyGithub.** The first version used PyGithub (LGPL-3.0, weak copyleft). + Swapped for a ~120-line `github_client.py` that calls the GitHub REST API + directly with `requests`, so the dependency tree is permissively licensed + only (MIT/Apache/BSD). Cost: a few more lines and manual pagination if the + open-PR list ever grows past one page (unlikely for a docs-PR queue). + +## Known limitations + +- The changelog entry is only as accurate as SuperDocs' summary of the merged + PR; the human review is the safety net. +- `git diff` fallback for changed files requires `fetch-depth: 0`; without it, + a docs-only PR may not be detected and the action may run when it should + skip (it will still skip if SuperDocs produces no change). +- The action does not auto-merge; a human must merge the docs PR. + +## Live-test findings (demo repo: avneeshjadhav04/docs-pr-demo) + +Verified end to end on a real repository with a real SuperDocs API key: + +- **Feature merge -> docs PR opens.** PR #8 merged, action drafted the entry + ("- feat: slugify names (#8)"), opened PR #9 with a one-entry diff.

Fixed by removing the expression from the input + description. (Found via run log, not docs.) +2. **Session-level `Content-Type: application/json` broke multipart uploads.** + `requests` will not override an existing Content-Type header when sending + `files=`, so the upload body went out as JSON and the server returned 422 + "Field required: file". Fixed by setting only the Authorization header on + the session; `json=` sets Content-Type per request. +3. **A completed job can carry `metadata.pending_changes: None`.** The AI + applied the edit directly (approval_mode was honored, but the job completed + with no pending-changes array), and `_parse_changes` crashed on None. + Fixed by treating None/missing as an empty list and logging the AI's + response text for diagnostics. + +Also observed: GitHub blocks Actions-created PRs unless the repository setting +"Allow GitHub Actions to create and approve pull requests" is enabled +(403 "GitHub Actions is not permitted to create or approve pull requests"). +Documented in the README as a setup requirement. diff --git a/extensions/avneeshjadhav04/superdocs-docs-pr-action/README.md b/extensions/avneeshjadhav04/superdocs-docs-pr-action/README.md new file mode 100644 index 0000000..6ade850 --- /dev/null +++ b/extensions/avneeshjadhav04/superdocs-docs-pr-action/README.md @@ -0,0 +1,126 @@ +# SuperDocs Docs PR Action + +A GitHub Action that drafts a documentation update with SuperDocs when a pull +request is merged, and opens a pull request with the diff for human review. +When nothing needs saying, it says nothing: the action skips entirely. + +Built for the SuperDocs task (round 2, engineer track). + +## What it does + +On `pull_request` closed + merged: + +1.
